For two months I have been having troublesome sinus issues. I am constantly blocked on one side, I have a constant, very bad, almost musty smell, some blood, and increasing pain. I was on a full course of anti-biotics, but the symptoms only got worse. I have been using the neti pot to try to clear my sinuses, but the mucus is mostly clear(with small amounts of green and bloody mucus), and the blockage doesn't get better(neither does the bad smell). I saw an ENT doctor and he said my sinuses looked fine, and a CT scan showed nothing. I'm at my wits end (and am partly convinced it's some sort of fungal ball), is there anything you can think of, or could you tell me what I should ask the ENT to look for when I go back?? Thanks.
